Context7: always up-to-date docs for Claude
A free, step-by-step template from Taha's reels — the exact tools, prompts and links, laid out so you can follow along and ship. Comment the keyword on the reel and it also lands in your DMs.
Hey! 👋 Here's what I promised you:
Context7 — the MCP server that keeps Claude's docs up to date for every library you use. The problem is well known: models are trained on old data, so they write you code with outdated APIs and mess up your project. Context7 feeds the fresh docs straight into the context, so Claude — even with an old model — works up to date against the newest versions.

- In the terminal, one line:
npx ctx7 setup --claude
It handles the OAuth, gets you an API key, and installs everything on its own. ✅
- After that, in any prompt, just add this phrase:
use context7
Example: Creili auth b Next.js w Supabase, use context7 — and it pulls the up-to-date docs by itself.
- Want a specific library exactly:
use library /supabase/supabase for API and docs
